To all whom it may concern: g

Be it known that I, GEORGE E. CAMPBELL, a citizen of the United States, residing at Chattanooga, in county of Hamilton and State of Tennessee, have invented certain new and useful Improvements in Rift-Splitters, of which the following is a specification.

My invention relates to an improvement in rift splitters, and the object is to provide a mechanism for shifting a gang of saws and splitters, which splitters are located one behind each saw on a rift machine, or on any machine which carries a gang or battery for sawing a log or cant into boards.

The object of a machine of this character is to provide means for sawing thick timbers into boards.

A. sawyer operating a saw mill will take a log and instead of sawing the same up into one-inch or two-inch boards, he will saw the logs into cants six oreight inches thick, and then pass them to a rift machine which has gangs of saws placed on sleeves, which saws are capable of being shifted so that the cents can be sawed up into boards of the proper thickness. a Y

The invention consists of certain novel. features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a top plan View; Fig. 2 is a detail view in perspective from one end; Fig. 3 is an end view showing one of the saws and splitters with the end plate removed; Fig. l is a top plan view showing the saws and splitters with certain parts of the frame broken away to more clearly disclose the parts; Fig. 5 is a top plan view showing the manner of mounting the splitters; Fig. 6 is a detail perspective view showing the lever for shifting the rift sleeve splitters; and Fig. 7 is a detail sectional view of the lever.

A represents the machine, and B represents the saw arbor. Mounted upon the saw arbor are sleeves 1 and 2, upon which are mounted saws 3, 3. The saws are shown in gangs of four, although any number may be used. Spacing collars 4 are inserted between the saws for holding them the re quired distance apart. The sleeve 1 is held stationary upon the arbor B by means of a set screw 5 and spline. The sleeve 2 is slidably mounted upon the arbor, and is connected thereto by spline 6. A set or gang of splitters 7, 7 are located in the rear of g the stationary sleeve 1, and are provided wlt-h spacing blocks 8, which are located between. the splitters and are fastened thereto by means 'of bolts 9, 9. The end blocks 8 terminate in a foot 10, which is bolted to 1 and 19, and are capable of movement endwise their brackets. Secured to the two rods 14 and 15 is a cross head .20, so that theyare held together andmove in unison. Connected to the cross head is a link 21, which link is connected to a lever 22. The lever. 22 is mounted upon a rock shaft 23, which extends to the front of the machine, and connected to the shaft23 on the front of the machine is a lever 24. A graduated segment 25 is mounted upon the frame and is provided with teeth 26, which are adapted to be engaged by a spring controlled handle 27 on the lever for holding the rockor rift splitting shaft at various positions.

Mounted upon the rod 14 is an arm 28, which is adapted to be received in a groove 29 in the sleeve 2. The arm 28 is fastened to the shaft by a set' screw 30 and a collar 31. The outer ends of each of the gang of splitters 7 and 11 are all arranged and mounted so that a splitter will be located directly behind each saw.

It is necessary that these splitters be located exactly behind the saw so that they will not interfere with the saws or cause binding. These splitters are preferably made of thin steel or iron, and are located exactly behind each saw in order to spread the boards apart as they are sawed and prevent their binding the saws and prevent the short pieces on each side of a gang from being thrown out of machine and injuring the operator.

By manipulating the lever 2d the shaft 23 is oscillated or rocked sufficiently to cause the lever 22 to be moved, thereby causing the rods 14 and 15 to be reciprocated for the purpose of moving the sleeve 2 and the saws and splitters toward or from the stationary saws and splitters 3 and 7. This mechanism 7 arm 28 can be raised and both gangs of saws can be removed from the arbor B through the circular clearance opening D in the side of the frame without disturbing the balance of the machine. Furthermore, it is impossible by this arrangement to shift the saws without shifting the splitters ex actly the same distance, thereby preventing the splitters from getting out of line with the saws, which would cause something to break.

Through the body of the stationary and movable splitters bolts 32 extend and are fastened thereto by means of nuts 34, collars 33 being interposed between the splitters and mounted upon the bolts 32 to prevent the splitters from becoming loose and interfering with the saws.

A bolt or rod 35 extends through holes 36 in the upper ends of all of the splitters, as shown in Fig. 4. It has its ends secured by nuts 37, 37, to the frame of the machine,

thus afi'ording a common means for the support of the upper ends of the splitters.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

' 1. The combination with a bed, a sawarbor and saw, of a sliding member located out of the path of the sawdust, means connecting the member to the saw, bearings supporting the member, said bearings located outside of the travel of said means, and maintaining the member in its plane of travel.

2. The combination with a bed, saw-arbor and saw, of a sliding member, located out two rods, means for connecting the rods to the saw, and'bcarings supporting the rods and located outside of the travel of said means. a

3. The combination with a bed, saw-arbor- G. E. CAMPBELL.
